Detailed Description

Per-entity cache of Geode's encoded-path output (and strokeToFill result). Installed lazily by RendererGeode at the encode call sites via get_or_emplace; removed automatically when the source ComputedPathComponent updates or is destroyed.

Lives in donner::geode (not donner::svg::geode) to match the other Geode types (EncodedPath, LinearGradientParams, …) that RendererGeode.cc references unqualified via geode:: inside the donner::svg namespace.

struct donner::geode::GeodePathCacheComponent::StrokeSlot

Stroke-slot cache. Holds both the Path::strokeToFill output path and its encoded form, keyed by the source StrokeStyle. Invalidated whenever the fill slot is (geometry change, via the entt signal), or on stroke-key mismatch (stroke width/dash/cap/ join change via CSS — the old key no longer matches the new one, so the next access regenerates).

Class Members
EncodedPath	strokedEncode	Cached encode of strokedPath. Produced by GeodePathEncoder::encode(strokedPath, strokeFillRule).
Path	strokedPath	Cached Path::strokeToFill output. Reused across draws of the same entity + stroke-key combination.
FillRule	strokeFillRule = FillRule::NonZero	Fill rule the stroke was encoded with. strokeToFill picks NonZero vs EvenOdd based on subpath topology, so this is derived and cached alongside the encode.
StrokeStyle	strokeKey	Equality key. Compared against the caller's StrokeStyle to detect stroke-parameter changes.
